Explosion Wounds 3 in Botched BHO Extraction Process

An explosion from a marijuana cook gone bad severely wounded three men and set a quiet Monrovia neighborhood on edge.

The house fire broke out at 5 a.m. Sunday in the 200 block E. Walnut Avenue, police said.

Police were investigating whether the occupants of the house were attempting an extremely dangerous method of using flammable butane to extract the hallucinogenic chemical tetrahydrocannabinols — or THC — contained in marijuana plants.

When authorities arrived, they saw a house fully engulfed in flames and three burned men in an alley and out front.

Police said the men were likely using a new method called butane honey oil to extract the potent drug from pot.

“The problem is, these people aren’t chemists,” said Monrovia Police Sgt. Nick Manfredi, a department watch commander. “They’re trying to do this without proper training.

“They hear from a friend or go on YouTube to learn how to do this and it could be catastrophe.

Residents were shocked as they have been working with city officials to keep the area clean.
